IMPROVEMENT IN BOBBlN-WINDERS.

Specification forming part of Letters Patent No. 198,153, dated December 11, 1877 application filed September 8, 1877.

To all whom it may concern:

Be it known that I, JOHN B. PRICE, of Thompsonville, in the county of Hartford and State of Connecticut, have invented an Improved Bobbin-VVinder, of which the following is a specification:

This invention relates to bobbin-winders for sewing-machines, and has special reference to the combination, with a rack and thread-guide, of a pinion adapted to reciprocate such rack and thread-guide alternately in opposite directions, to present thread to the bobbin.

Figure 1 represents, in top view, a bobbinwinder provided with my invention; Fig.2, a side" elevation, and Fig. 3 an under-side View thereof; Fig. 4, a detail showing the rack and thread-guide; Fig. 5, a detail of the pinion to move the rack, and Fig. 6 a view of the connecting worm-shaft.

The frame a, the bobbin, and the devices to sustain and. rotate itare substantially as in other I winders. I provide the shaft 1) with worm-teeth c, to engage a worm, d, on an upright connecting-shaft, 6, having at bottom a lantern-wheel or other suitable pinion, j, which rotates a pinion, g, having, in connection with it, teeth h, that, by their engagement with the teeth 2'- j of the rack-bar 7c, reciprocate the rackbar and its thread-guide l alternately in opposite directions, in order to present the thread .to the bobbin from end to end between its heads.

The segmental series of teeth It (shown as composed of pins projecting from the wheel g) engage the row of teeth j, and then the row of teeth i of the double rack-bar, and reciprocate it and its attached thread-guide horizontally in a line with the axis of the bobbin, whereby the thread is delivered more evenly and regularly than would be the case if the threadguide moved in the arc of a circle. The rackbar is seated in the under side of the frame, and is held in place by the pinion g, which is supported by the screw-stud n.'

I claim-- 1. In a bobbin winder, the combination,

with the horizontally-reciprocating rack, pro-- vided with two rows of teeth, 73 7, and thread guide, of a series of segmentally arranged teeth placed between the rows of teeth of the rack-bar, and adapted to engage first one and then the other row of teeth, to reciprocate horizontally the rack and threadguide alternately in opposite directions, substantially as and for the purpose described.

2. The worm-shaft b, the connecting-shaft 0, provided with worm-gear d and pinion f, and the pinion g, provided-with teeth h, in combination with the rack-bar, having a double row of teeth and a threadguide, substantially as and for the purpose described.

3. In a bobbin-winder, the combination, with the shaft b and its worm, of the vertical connecting-shaft, provided with a worm-gear and pinion, to operate a thread-guide, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN B. PRICE.
